One of the news shows said that the ceiling for the 777 was lower than 45000 feet. One theory I saw floated around was they took it to 45000 for a few min to kill the passengers. The crew would wear the supplemental oxygen.
Another expert said the radar data they are using to form the altitude changes was not accurate.
It wouldn't kill the pax, some business jets have a service ceiling of >50k ft. Remember that the plane is pressurized, they are not breathing atmospheric oxygen. If that were the case they'd be dead at >~26k feet without acclimatization.
I would imagine the commercial jet would be difficult to fly at >40k ft due to the air density though.
If it is ever proven that terrorism was involved, VM will throw a party at his house and start no less than 30 threads on VN celebrating that he was right.
I'm not saying he is wrong. There is certainly enough evidence that the possibility of terrorism, or at least some act of angry personal vengeance, is in the top 5 scenarios right now.
Its just that he seems to really want it to be that for his own agenda, which I find disturbing. I think he is far from alone. There seems to be almost this sense of glee from the neocon far right at the prospect.
If the cabin pressure changes rapidly for the worse I believe the oxygen masks deploy. Thankfully I've never been in that situation to know first hand. It's not far fetched though to think thats what they did.
About the radar data I would LOVE to know what they were looking at. If the transponder I don't know where they were getting their altitude information from without analyzing the raw data returns. For all intents and purposes a plain surveillance radar is just going to tell you an object is out there with no altitude information. The combination of secondary radar (MODE-S/BEACON) is what allows most ATC to know who they are looking at and at what altitude. I work on this stuff for the FAA and I have a feeling the systems in use over there are extremely antiquated.
And the sat updates..how does a satellite receive information to adjust itself for better communication with an aircraft yet somehow that data cannot be used to get a good idea where it was? I am assuming the "Adjustment" was something like "look over Indian ocean"..
